Association between Breakfast Skipping and Body Weight—A Systematic Review and Meta-Analysis of Observational Longitudinal Studies
Round 1
Reviewer 1 Report
Dear Authors
The study is giving new evidence on the relationship between overweigh/obesity and skipping breakfast, the study focused on adults; it would be goof if you include school children age groups.
However the study is excellent although the sample size is small.
I recommend to expand the introduction and include more data on obesity and its relation to NCDs as a burden, and link it with the WHO recommendations.
You may need to add few recommendations to the public, as an outcome to your study.

Reviewer 2 Report
Dear Authors,
Breakfast skipping and body weight is an important topic and this review and meta-analysis provide an overview of the current state of knowledge.
The following minor revisions are recommended for improvement before publication.
Introduction
line 33: The link for reference is not working. Please check if more recent data are available (World Obesity, IOTF wbsite?)
lines 53-61: In this section I would like to have a little more information on the relationship between breakfast and body weight: potential mechanism, hypotheses, etc.
Materials and Methods
Why the following criteria for the frequency of eating breakfast were adopted: ≥ 3 days and ≤ 2 days? Information is lacking on this, please explain.
Results
This section is well described, however, analyzes were conducted on the basis of a few studies only and with some differences in methodology. It is not the authors' fault, but it should be emphasized in the discussion as a certain limitation of the work.
Discussion
General: Are the results obtained by the authors consistent with the results of similar analyzes but concerning the pediatric population?
